Oakland County Sheriff Michael Bouchard said Friday afternoon that officials are trying to find dental records of the woman from before she moved to Michigan to confirm the identity.

"The focus is going to be to identify," he said.

He did not release her name, but online records show 49-year-old Pia Farrenkopf lived at the home on Savanna Drive.

For at least five years, her body was believed to have been in the back seat of her Jeep clothed in a heavy jacket and jeans. The body was discovered Wednesday in the garage of a ranch home where she lived alone.

"She didn't have children or a husband or a pet when she was here," Bouchard said. "Proceeding that, I don't know."

The woman was a contractor with the now defunct Chrysler Financial and was at work last in September 2008, Bouchard said.

Investigators are looking into what she was doing immediately prior to her death and what caused her death, which may never be determined.

Farrenkopf has family on the East Coast and a sister in the Boston area has been contacted about her death.

"They hadn't communicated for years," Bouchard said, adding it appears the two were estranged.

The Free Press was not able to reach any family members who knew her, but talked to a few people who shared her last name and who live in Massachusetts. They said they had a big family, which was spread out across the country.

It's unclear how long Farrenkopf had lived in Michigan, but a business document filed with with the state in July 2003 listed her name and address in Pontiac.

Police said the woman's bills were automatically deducted from her bank account, and residents of the quiet middle-class Pontiac neighborhood said they didn't notice anything amiss.

Eventually, the $54,000 in her bank account ran out, and the house went into foreclosure, leading to the gruesome discovery this week when a contractor the bank sent to check out the house discovered her remains.

An autopsy showed there was no trauma to the body. Her case is being investigated as an an unknown death.
